ROTARY WEIGHT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 775,008, dated November 15, 1904. Application filed April 27, 1904. Serial No. 205.257. (No model.)

`To all whom it may concern.:

Be it known that I, GOTTLIEB P. KAHLER, a citizen of the United States, residing at Armington, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Rotary lVeight-Motors; and I do hereby declare that the following is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. This invention pertains to a combined steam and weight motor.

The object of the invention is to produce a power-giving device for driving machinery of any kind having movable weights operated by .steam-pressure.

` A further object is to provide a rotary weight-motor in which steam is used to shift the weights to the position for work.

A further object'of the invention is to provide a rotary motor operated by weights shift-l able toward and away from the point about which the motor revolves.

Another object, and an importantone, is to use steam in a rotary weight-motor, upon the pressure of whih the motor is dependent for its operation.

In the appended drawings, Figure lis a side elevation of the motor. Fig. 2 is a transverse vertical section thereof. Fig. 3 is a per spectiveyiew of a weight, showing rods on which it slides. Fig. 4 is a cross-sectional view of a portion of one of the weights, showing socket and pipe therein and a piston-rod within the pipe. Fig. 5 is a plan view of a part of a weight, showing cross-section of the pipe and piston-rod illustrated in Fig.l 4. Fig. 6 is a cross-section of a portion of the rim of the motor-wheel and a hollow spoke used as an oil-receptacle. Fig. 7 is a side view of shaft which supports the motor and upon which the motor revolves'. Fig. 8 is a crosssectional view of the shaft shown in Fig. 7, showing the hub of the motor-wheel thereon, also in section. Fig. 9 is a sectional view of a pipe, showing a piston therein and pistonrod connected with said piston. Fig. l0 is a modilication showing a belt-pulley.

A indicates the rim of a wheel having pairs of spokes B, which, as shown in Fig. 2, are

screwed into the hub O and secured by the nuts D or in any other good manner. The said spokes, as shown. are placed near each end of the hub, and in the middle of the hub are radiating tubes or pipes, each of which lies between a pair of the said spokes B, be

ing open at their outer ends and may b either cast with the hub or screwed thereinto, as desired.

At F are a series vof weights connected in pairs by means of rods G, of which there are four, two being at each side of the hub. The Weights are provided with holes through which the spokes B extend, the weights being placed on said spokes before the latter are secured in place. As shown in Fig. 1, the weights which are diametrically opposite the center of the wheel are the ones that are connected, the rods G, before mentioned, being screwed into the weights to firmly secure the latter a fixed distance apart.

' VWithin the tubes E, which are bored out smooth, Yis a piston H, Figs. 2 and 9, carried by piston-rods I, made in two sections, the lower end of which rests in a socket J of the weight. This is clearly shown in Fig. 4, as well as in Fig. 2. The socket J is at the bottom of a hole K, drilled or cast in the weight, into which the tube E enters, as will be hereinafter described. The end of the piston-rod which rests in the socket J is grooved at L to receive the head of a screw M in the bottom of the hole K, one side of the head being cut away, as shown in Fig. 5, to let the head of the piston-redentor the socket, and it will'be seen that a half-turn of the screw prevents the head leaving its seat. A union N, F-ig. 9, allows the two portions of the rod I to be separated when desired. The piston-head comprises a portion fr, secured to the rod, followed by'a threaded portion z', and between these sai portions is placed a leather ring y', which may be enlarged as often as desired by screwing the portion z tighter in order to make a more tightly fitting packing, all of which will 9 be understood. The shaft upon which the wheel A revolves is indicated at P, being shown clearlyin Figs. 2 and 7 Said shaft is carried in supports Q and secured against turning by set-screws it or other good means.

ICO

From each end the shaft is bored longitudinally, the end of one bore, S, turning upward and terminating at the periphery of the shaft, the other bore, T, turning downward, as indicated. A pipe is screwed into each end of the shaft thus provided, one serving as the steam-supply and the other as the exhaust port. The bore of each tube E is extended through the hub C, so that they may communicate with the bores S and T of the shaft P, as shown in Fig. 8.

1t will be noted that in Fig. 1 three of the weights are resting against the rim of the Wheel, while the others are nearer the center of the wheel, for since the pairs of weights vare connected it follows that when one of a pair is distant from the shaft P the other must be near said shaft, and vice versa. 1n order that the weights may approach the shaft as N near as possible, they are provided with the in order that the This may be seen figures also it will holes K, before described, ,tubes E may enter them. lin Figs. 1 and 2. In these be seen that the tubes E occupy a vertical position-ffl. e., the top and bottom ones are i lcommunication with the bore S and T, respecjtively. Now steam entered into the bore S fwill enter the tube in communication there- `with and act upon the piston H, thus raising such piston and the weight above it. This movement must also raise through the rods G forcing out any steam in the lower tube through the bore T of the shaft. The wheel A being in motion toward the right as viewed in Fig. l, by reason of the weights at the right being farthest away'from the center, the weight which has linst been raised will now exert power, while its companion at the bottom of the wheel will have been raised to the broken-line position, where its weight will not be in position to exert power. As each weight reaches the top of the shaft, where its tube will be brought into communication with the bore S, it will be raised, as herein described, while the weights at the bottom will be raised, their work having been accomplished by the time they reach the bottom of the wheel. It will be seen that these actions will be continuous as long as steam is admitted to the shaft. The bore S where it ends at the surface of the shaft is enlarged, so that steam reaches the tubes E and begins its work of raising the weight immediately, so that there will be no time lost. ln broken lines in Fig. 8 and in Fig. 7 the shaft is shown with a groove U. This groove extends about one-half of the way around the shaft and communicates with the bore T. It will be understood that the tubes E are filled with steam to hold the weights out in position, and after the weights have reached a position in line with the shaft horizontally they will remain near the rim of the wheel and then need no pressure to hold them out. Therefore the steam is allowed to iind an outlet, which it the lower weight means of the groove U described, so l that by the time the weight reaches the bot- 1 tom of the wheel the steam is entirely exl hausted and no counterforce is presented to l prevent the upper weight being raised by the inlet of steam to the tube that corresponds therewith.

l The motor does not depend on steam for its power, but for raising the weights, the latter l does by furnishing the power by the force of gravity. Very little steam is necessary to raise the weights; but the pressure is such that the action is very quick, and in order that there may be no jar in the movements thereof springs V are provided, one end of each being secured to the hub C and the other to the weight, one being at each side of the latter. (Shown in Fig. 2.)

The shaft and hub are made to fit steamtight and are kept lubricated by means of two of the spokes B, one at each side of the wheel, which are made hollow and kept filled with oil. These hollow spokes pass entirely through the hub C, as shown in Fig. 2, and a screw YV serves to close the ends at the rim of the wheel. The steam supply may be haust returned tothe fire for assisting in creating a draft. l A belt may be placed upon the wheel A and power thus transmitted to any piece of ma chinery desired. By increasing the size of the wheel and the weights power of any amount can be supplied. l

Evidently many changes may be made in the construction of the device, since I do not confine myself to the particular arrangement shown and described; but the idea of a motor operated by weights with steam as the power for placing the weights in position to dowork is my wish.

The motor is self-governing, for the reason that if it should begin to run too fast the tubes E would pass over the port S so fast as to miss taking steam, with the result that the weights would not be raised, and in consequence the wheel would have to raise a Weight at the other side of the wheel, and this of course would at onceretard the momentum of the device. The steam would then be permitted to enter the next succeeding tube E to raise a weight, and so on. To reverse the drection of revolution of the motor, it is only necessary to 'stop it and give it a start in the opposite direction. The entrance of steam will then keep it moving as before.

l 1n Fig. 10 is shown a slight modification of the hubC. Said hub is extended beyond the wheel-rim and is provided with a belt-pulley 0, the shaft P being also elongated to bring it l out to the bearing Q, which is likewise moved l out to accommodate the change in the parts. By belting from the motor in this manner more power can be obtained, as is evident.

The rim of the wheel may be eliminated brought from the boiler, as usual, and the ex- IOO IOS

from the device, as it is not absolutely necessary to the operation of the motor.

Suitable stops could be placed on the spokes to arrest the outward movement of the weights, if desired.

Other, means may be substituted for the springs V, if desired, as by placing springs around the spokes againstthe rim of the wheel against which the weights may strike.

Although I have spoken of steam as the power for raising the weights, I may employ compressed air and even water and the desired results will still obtain.

Having thus described my invention, I claim- 1.
